Building a simple game around a spin
A spinning wheel is a natural game mechanic on its own: it adds suspense to an otherwise plain random choice, which is why so many party games and game shows are built around one. You don't need a purpose-built game app to use that mechanic — any list of outcomes (dares, trivia categories, point values, challenges) works as wheel entries.
Because the entry list is just plain text, the 'game' can be whatever you design around it: a dare wheel for a party, a trivia-category wheel for game night, or a point-value wheel for a classroom review activity. The wheel just handles the fair, suspenseful part.
